Chris Brown shoves woman who tried to kiss him.

Chris Brown got physical with a woman who jumped in front of him during a nightclub appearance in Houston — and even though she initiated the contact … it was a questionable reaction from Chris.

Chris performed at Limelight Houston over the weekend, and while he and Karreuche Tran were walking through the crowd … a woman stepped in front of him and reached out … apparently trying to kiss him.

Chris gave her a pretty hard shove with his right forearm to move her out of the way.

It doesn’t look like the fan was hurt. Obviously, not a smart move for someone with Chris’ track record to mix it up with fans — especially women — even when they start it.
